共沉淀法制备HA/β-TCP双相生物陶瓷粉末新工艺研究
Synthesis of HA/β-TCP biphasic bioceramic powders by a modified co-precipitation method
【摘要】 在加热条件下,通过调节Ca(NO3)2 (NH4)2HPO4 NH3H2O H2O体系的pH值,制得了不同HA和β TCP比例的纯双相粉末,并对其反应历程进行了初步研究。新工艺和常规方法比较,大大缩短了陈化时间,反应重复性好。
【Abstract】 By means of heating the reacting solutions and adjusting the pH values of the system of Ca(NO3)2(NH4)2HPO4NH3H2OH2O, the biphasic bioceramic powders with different Ca/P ratios have been synthesized. The reactions have a good repetition and the resulting precipitates require a shorter ageing time. In this paper, the reacting mechanism has also been discussed.
